Here are 25 interesting psychological facts about human behavior and cognition, along with brief explanations of each:

1. The brain is wired to pay attention to negative information more than positive information.
2. People are more likely to remember information that is presented at the beginning or end of a list or sequence (the serial position effect).
3. Social rejection can cause physical pain and activate the same brain areas as physical pain.
4. People tend to believe information that confirms their existing beliefs, and discount information that contradicts their beliefs (confirmation bias).
5. The mere presence of others can improve performance on simple or well-learned tasks, but hinder performance on complex or unfamiliar tasks (social facilitation).
6. Our memories are not perfect recordings of events, but rather are influenced by our expectations, biases, and other factors (memory distortion).
7. People tend to underestimate the impact of situational factors on other people’s behavior, and overestimate the impact of personality traits (the fundamental attribution error).
8. Multitasking is less efficient than focusing on one task at a time, and can reduce productivity and increase errors.
9. People are more likely to comply with a request if it is framed as a small, initial commitment (foot-in-the-door technique).
10. People are more likely to take risks when they feel anonymous or part of a group (deindividuation).
11. Our emotional responses can be influenced by our facial expressions, and vice versa (facial feedback hypothesis).
12. People tend to overestimate their own abilities and knowledge, and underestimate the abilities and knowledge of others (the Dunning-Kruger effect).
13. People tend to remember events that are emotionally charged or significant more vividly than mundane events (flashbulb memories).
14. People are more likely to comply with a request if it is made by someone who has previously done them a favor or given them a gift (reciprocity).
15. People tend to conform to the opinions or behaviors of a group, even if they disagree with them (conformity).
16. Our attitudes and behaviors can be influenced by the presence or behavior of others, even if we are not consciously aware of it (priming).
17. People are more likely to attribute their own successes to their own abilities or effort, and their failures to external factors, whereas they are more likely to attribute other people’s successes to external factors and their failures to their own abilities or effort (self-serving bias).
18. People are more likely to remember information that is presented in a visually appealing or emotionally evocative way (the von Restorff effect).
19. People are more likely to comply with a request if it is made by someone who is seen as an authority figure (the Milgram experiment).
20. People are more likely to remember information that is repeated or rehearsed multiple times (the spacing effect).
21. People tend to overestimate their ability to predict future events or outcomes (the illusion of control).
22. People are more likely to remember information that is personally relevant to them (the self-reference effect).
23. People are more likely to conform to the opinions or behaviors of a group if they perceive the group as high-status or important (social influence).
24. Our mood and emotions can be influenced by the colors, lighting, and other environmental factors around us (color psychology).
25. People are more likely to remember information that is presented in a narrative or story-like format, rather than as a list of disconnected facts (the narrative bias).
